[PATCH 1/3] ARM: dts: imx6ull: fix the i.MX6ULL UART8 configuration

Lothar Waßmann LW at KARO-electronics.de
Fri Jan 26 00:23:50 PST 2018


UART8 on i.MX6ULL is not located on the SPBA bus like on i.MX6UL but
on the (otherwise unused) AIPS-3 bus.
Create the appropriate AIPS-3 bus configuration and move the uart8
definition where it belongs.
